TEHRAN — Abbas Jafari Dolatabadi, Tehran’s prosecutor general, announced on Saturday that Iran had released four Iranian-Americans as part of a prisoner exchange with the United States.

“In line with ratifications of Iran’s Supreme National Security Council and the Islamic establishment’s general expediencies, four Iranian prisoners, who hold dual nationality, have been released within the framework of a prisoner swap,” Dolatabadi said on Saturday, Press TV reported.

Dolatabadi did not identify the four, but ISNA news agency said they included Jason Rezaian, the Washington Post correspondent; Amir Mirzayee Hekmati, a Marine veteran; and Saeed Abedini, a pastor; and Khosravi.

An informed source at the Judiciary confirmed to ISNA the release of Jason Rezaian and Saeed Abedini. Nasser Sarbazi, a lawyer, confirmed the release of his client Saeed Abedini.

Iranian media reported seven Iranians were also freed. According to IRNA, a source named Nader Madanlou, Bahram Mekanik, Khosro Afghahi, Arash Qahreman, Touraj Faridi, Nima Golestaneh and Ali Sabounchi as the seven Iranian nationals who have been released.

The exchange was orchestrated to coincide with the expected announcement of the lifting of nuclear sanctions against Iran, the most important phase of the nuclear deal reached with world powers in July.

The incarceration of the Iranian-Americans had become an increasingly bitter side issue.

According to the prisoner deal, Interpol will also stop its probe to arrest 14 Iranians, ISNA said.

Rezaian, 39, a California native and dual citizen of the United States and Iran, was the Post’s bureau chief in Tehran in July 2014 when he was arrested. He was charged with spying on Iran’s nuclear program and gathering information about violations of international sanctions against Iran.

He was convicted in October after a closed trial.

Executives from 25 news organizations recently sent a letter to Secretary of State John Kerry urging him to press Iran to release Rezaian, the New York Times reported.
